Comparison between the GPS L2 signal fades of GNSS stations situated in the same geographical area depending on their receiver. There are four stations from Spain (left panel), six from the northeast of North America (middle panel) and four stations from the northwest of Europe (right panel). GNSS receivers from the same brand are represented in the same colour. The legend indicates the name of the station, the model of its receiver and the solar elevation angle at the time of maximum SRB emission. It can be noticed how receivers from the same brand tend to behave similarly. The SRB corresponds to Event 03 in Table 1.
